Pests or rtn

[GHOSTLY]

With my recent and big changes from 6g to 20g ive had a couple die offs. I did buy used lr, so no guarantee it isn't pest Free. I thought all my die off happened but another piece seems to have been starting. Is this more rtn/stn or pest markings.

Photo with light is now at 9:47pm and the dark one was around 11am this morning.

I am dosing phosguard so i had a small phosphate swing but my parameters are
Alk 8.3
Ph 8.1 (trying to bring up via surface agitation)
Calcium 420
Mg 1400ish
No3 10 (wc and slowly been bringing down with wc from 30s)
Po4 .25 (bringing down from .7, been slowly bringing it down for a while)

Just throwing this out there because it may be worth a try. No idea the cause but I had a piece that developed a similar die off in the middle of the piece vs top or bottom like I usually see. I went in and scraped all around the area to expose the flesh (?) and the coral healed and grew back over the area the dead area.

Crappy pic but it shows the area almost fully healed.

I had a similar issue initially and it was because the spot was shaded and I wasn't receiving enough flow, hence the new pump. The reason I suspect rtn for mine or pests is just becsuse of the way it presents itself. I did superglue over it so hopefully that saves it

Dropping phosphates too fast will do this. Phosphate removers are notorious for this as they also strip other trace minerals which are responsible for other cellular activity.

Thats what I thought, i made sure to underdose but I probably should of switched to gfo. I have been supplementing with aminos and trace elements to compensate and to feed.

The spot wasn't big enough that I wanted to frag the colony so I ended up supergluing over. Think its worth doing an iodine dip in case?

Yea, the issue is that from dosing the elements to getting them to a bioavailable states takes some time, where as the absorber works immediately upon introduction. So the lag time and the rapid change in gradients probably made the coral unhappy.
An iodine dip may help to sterilize, but will also be stressful on the coral. I would remove the phosphate absorber and monitor the coral’s condition. If you dip it, it may be a good time to try and frag what you can save too

Ill maybe hold off on the iodine for now, i did remove the phosphate remover a couple days ago

The damage had been spreading very slowly so I superglued the dead tissue and over some healthy tissue to see if I can block it off. If I notice more spread ill try to frag off. Ill send some pictures today around 5 but hopefully it bounces back
